Real-time news with tone analysis, brand safety, and narrative shift signals for AI agents.
Real-time news with tone analysis, brand safety, and narrative shift signals for AI agents.
An MCP server that gives any agent real-time news plus the contextual intelligence to use it well — tone distribution, emerging stories, narrative shifts, spike alerts, and tone-over-time charts — powered by Overtone's publisher network.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| news | Articles on a topic, each tagged with tone, brand-safety signals, article type, and concepts. Use for "what's happening with X". |
| tone | Emotional tone distribution across recent coverage of a topic — happy, funny, hopeful, informational, angry, sad, fearful, plus the dominant_tone. |
| pulse | Pollable spike detector. For each watched tone (default angry / sad / fearful), returns spike_ratio vs. a baseline window and a boolean spiking. alerts is populated only when spike_ratio >= 1.5 with meaningful volume. |
| emerging | Concepts appearing in the last 24 hours that had zero coverage in the prior 48 hours — candidate emerging stories. Cluster-filtered to ≥3 articles and ≥2 sources so single-article noise doesn't leak through. |
| velocity | Concepts whose tone distribution has shifted most sharply between the prior 48 hours and the most recent 24 hours. Answers "where is the narrative turning?". Ranked by shape-normalized L2 distance, so a uniform volume ri |
| timeseries | Tone trajectory over time for a topic. bin is hour, 6h, or day. Returns an ordered series of per-bin tone averages, article_count, and dominant_tone. |
| report | Called silently *after* the agent presents articles to the user, to log which displayed_urls it actually showed. Helps Overtone understand what content is most valuable to agentic clients. |
| Variable | Description | Required |
|---|---|---|
| OVERTONE_NEWS_API_KEY | Credential the server authenticates with. | Yes |
| OVERTONE_NEWS_API_URL | Endpoint or connection string the server talks to. | Yes |
